2011 stalling at slow speeds, hunting idle, restarts every time
Got 2011 with 205k, tuned and deleted.
Truck runs great, good power, no smoke, no leaks, no codes
Have a problem tho, engine idle is pretty erratic. It will start and idle perfect at 600ish, steady.
When I start driving no matter if hot or cold motor, and while still at slow speed, if I lift foot off throttle, the idle bounces 600-800 few times, and then settles at 600 most of the time.
Occasionally idle bounce goes as low as 400, and some of those times it can't catch itself and it stalls out. Restarts immediately like nothing happened.
When at speed, and lifting off pedal to coast, RPM would bounce couple of times and then settle. At first I thought it was from downshifting. but indicator is steady in 4 for example and RPM is bouncing anyway
Does anyone have same symptoms, or knows where to look
There are no error codes. I have tried a known good MAF sensor, same symptoms as with my original one.

Maybe take it to that dealer, and have them do some troubleshooting
